Autonomous heating from gas boiler, is possible only at the correct connection and grounding of the unit. There are several power supply circuits of gas boiler - from 220 V.' network, from the generator, with use of the UPS. Grounding can be executed as on the ready metal design buried vertically to the earth and on specially prepared triangular metal system.
How to ground gas wall boiler?
Grounding for gas boiler is indispensable condition of normal and safe operation. In certain cases (at connection of the generator), the unit can not be started without high-quality grounding. Besides, the unit housing constantly accumulates static electricity which action is unpredictable and is inadmissible in working conditions with the gas equipment. Even if the lack of grounding will not lead to ignition, automatic equipment can fail.
The grounding device for gas boiler
To bring grounding to gas boiler, the certain experience in electrical equipment is necessary. Also it is necessary to know requirements for grounding of the gas boiler equipment:
- Up to 50 Ohms (sand);
- Up to 10 Ohms (clay).
It is necessary to distinguish what is called working grounding which is required for functioning of sensors of ionization of flame, and protective grounding which removes static stress from the body.
As the ground wire it is possible to choose the ready metal design buried to the earth. It can be the pipe or corner driven vertically.
It is forbidden to use engineering systems as the ground wire!
For natural ground wires it is necessary to create two points of contact with boiler.
It is more difficult to ground the boiler, than electric stove or other household appliances. Here it is necessary to maintain precisely certain indicators of resistance of the conductor and conductivity of soil.
Now it is very popular to make triangular grounding of the gas equipment ready sets from copper pins and strips. At the same time on the place of tops of two-meter isosceles triangle, pins are driven in, connect strip and the grounding pin exit to building socle is created. The earth wire from the unit is fixed on pin.
Connection of power supply on gas heating boiler
It is enough to observe requirements imposed to the electroadjusting equipment to connect gas boiler to the power supply network:
- High-quality working grounding;
- Time cut-out.
The switch has to be in the protective body and be located in the safe place in case of break of the heat carrier.
The additional equipment depends on electric energy source. If power supply goes from the central network, it is necessary to install the stabilizer for normalization of sinusoid of current.
It is obligatory to do grounding on boiler contour. If in cord there is no 3rd wire, the grounding cable is connected to the boiler body. The cable has also to is in protective gofroshlang.
You watch closely phases. If to mix phase and zero, the boiler not to be started!
Also the UPS will be not superfluous, in that case if interruptions in delivery of line voltage are observed.
When powering from the generator, the stabilizer is not necessary, it is replaced by the resonant filter and frequency trim of the generator. At installation of the generator, on it it is necessary to add more consumers that the unit did not work in single, it leads to fast development of motor potential.
